Qs on the M60 and rebuilds.
Tried to do a search on M60 rebuilds. Basically mine is coming along nicely, its about 18,000km from 200,000kms. It runs fine and all, but I want to know when is a good time to rebuild it? Should it be a preventative rebuild say at 250,000 or 300,000kms? Or just drive it till it starts to loosen up or when it brakes something inside?

feed it good oil in a timely manner service the cooling system and take care of the various leaks vacuum/oil/coolant and it will probably out live the car it's bolted to, one thing to do if it's not been checked is the looseness of the oil pump bolts, the pump can literally fall off and starve the engine

eek, you're barely past 100 miles and you're worried about a rebuild??? You know, the more I drive my car the more I feel that BMW is an engine company above all else. To me the M60 is an absolute jewel. I don't get to drive many expensive new cars, but of all the cars I have driven nothing even comes close in terms of sound, refinement, power, anything you can think of... and mine has 270 kms on it.
Watch I say this and tomorrow a conrod snaps... (uh oh, fingers crossed, knock on wood, pray to the stars haha)

Just trying to plan ahead.
I am confident that the m60 can make it 300 to 400k clicks just on good maintenance and servicing, but I was just asking the question whether peeps here do rebuilds on it based on a mileage interval or a till it breaks mentality.Originally Posted by Traian

post your compression test results. I am sure then you will get everyone here telling you that you are nuts. Something I already know.

My experience has been, as the mileage builds up on an engine it loses power, gets noisy, runs rough and starts to leak. I ran a Datsun 240z (straight six) to the point where the compression was so low I had to use starting fluid to get it running every morning and everyday afternoon after work. It was a daily driver.
Nothing ever broke, it just wore out.
When I finally did change the engine I tore apart the old one and measured up to .0011" bore to piston clearance on numerous cylinders. It should be .003 to .005" max new.
The rings were completely worn out and a few were cracked.
So my point is, "IF IT AIN'T BROKE, DON'T FIX IT".
Why create an uneccessary expense, an expensive one at that, to your budget if it isn't required? Save your money for the transmission job and suspension rebuild you'll be doing in the future instead.
There comes a point when running a tired old sick engine will no longer be economical from a practical standpoint, (i.e. dumping gallons of oil in it per week). You'll know it when the time comes. In the mean time, DRIVE!!

got the parts.. putting it together
$hit.. won't start
we'll figure it out.. probably something small
damnit.. still can't figure it out..
Running out of time .. getting colder...
Bought the correct tools to set the timing, turns out one head was 180 off
Started right up
Basically if you need any help rebuilding it, you can ask me. I kind of knew what I was doing
